Question 4. A bin contains 400 colored erasers that fit on the ends of pencils. The numbers of erasers of each color is as follows. color Number Green 88 (i) (ii) Blue 60 Red 160 Yellow 92 a) A random sample of 25 erasers is selected, with replacement, from the bin, find the probability that: exactly 2 erasers are green; at most 3 erasers are blue (4 decimal) ;(use excel and write the function in answer sheet) (iii) between 8 erasers and 12 erasers, inclusive, are red. ;(use excel and write the function) b) Erasers are selected at random, without replacement, from the bin until 5 yellow erasers are obtained. Give two reasons why a binomial distribution does not model the number of erasers selected.
